wa ren-snare rnornrrnn AND vnnrrra'roni Application fi led January This invention relates to new and useful improvements in a motor craft propeller and ventilator.

Qne object of the invention is to provide a device of the character described specially designed for use on water craft for ventilat and assisting in propelling the same,

cl fith the above and other objects in view this invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying, drawings, wherein Figure 1 shows a fragmentary plan view of the device, partly in section, and

Figure 2 shows a side view thereof.

Referring now more particularly to the drawings, wherein, like numerals of reference designate similar parts in each of the figures the numeral 1 designates a floor or deck of a boat, or other water craft, and the numeral 2 designates a motor mounted thereon. A drive pulley 3 is fixed on the motor shaft 4 in alignment with the pulley 5, which is loosely mounted on the line shaft 6. Splined on the shaft 6 there is a cone clutch member 7 which is operable into and out of frictional engagement with the pulley 5 in the usual manner, through the shift lever 8. The shaft 6 may thus be operatively connected with or disengaged from the motor 2.

The numeral 9 designates a suction tube, adapted to be connected with the cabins, or compartments of the vessel to be ventilated and the rear end 10, of this tube is downwardly turned and its discharge end 11, is rearwardly turned and submerged in the water.

Incorporated in this tube there is a suction fan 12 whose shaft has a belt pulley fixed thereon. 1

The numeral 14 designates a counter shaft which has a pulley 15 fixed thereon aligned with the pulley 13. The counter shaft also has a pulley 16 fixed thereon aligned with the pulley 1.7 which is fixed on the line shaft 6. The belts 18, 19, and 20 transmit rotation from the motor to the line shaft, from the line shaft to the counter shaft, and from the counter shaft to the fan pulley, respec tively.

The fan 12 creates suction through the tube 9 and sucks the impure air from the compartments with which it is connected.

Incorporated in this tube there is a casing, 21, which has verticallyaligned hearings in which there is vertical fan shaft 22.- Enclosed within the casing 21 and fined on said shaft there is the turbine 23 disposed so that the current passing through the tube 9 will rotate it and the shaft 22, as well. Fixed onto the lower end of the shaft 22 is the conventional overhead fan, having the inclined vanes 2a, which serve to keep the compartment, in which the fan is located, cool The tube 9 has a lay-pass 25 around the casing 21 and there is a gate valve 26 adapted to control the passage of -air through the casing 21. By closing said valve the air, current,may be diverted through the by pass 25 and the fan 24 thus stopped. It is to be noted that the tube 9 may have a sutiicient number of branches to make provision for ventilating any or all of the compartments of the vessel, as well as for driving any number of fans, as 24, desired. Y I

One end of the line shaft 6 has the spaced friction discs 27, 27, fixed thereon whose facing sides are cone shaped and between them there is the driving cone 28 which is fixed on the adjacent end of the shaft 29. Thisshaft is mounted to rotate in the bearings 30, 31, the latter of which is located adjacent the cone 28 and is eccentrically mounted in the ring 32. This bearing 31 may be rotated through the hand lever 83 so as to shift the cone 28 into frictional engagement with either of the discs 27, 27, and thus reverse the rotation of the shaft 29.

There is a propeller shaft 34 disposed parallel with the shaft 29 and fixed on it there is a pulley 35 aligned with the pulley 36 fix-ed on the shaft 29. A belt 37 operates over these pulleys and transmits rota tion from. the latter to the former. The shaft 34 has the propellers 38, 38, fixed thereon and the counter shaft- 14 has the propellers 39, 39. fixed thereon.

These propellers assist in propelling the vessel along, particularly in the case of small craft. The discharge of air from the submerged discharge end of the tube 9 also assists somewhat in propelling the vessel.

l vhat I claim is:

1. A device of the character described including a ventilating tube, a current generator associated with the tube, a motor for driving said generator to create a current through said tube, a turbine associated with said tube and adapted to be driven by said current, a. tan operatively connected with and adapted to be driven by said turbine.

2. A device of the character described including a ventilating tube, a current generator associated with the tube and adapted to create a current therethrough. a turbine associated with said tube and adapted to be rotated by the current passing therethrough, a fan adapted to be driven by the turbine, said tube having a by-pass around the turbine, a valve adapted to control the flow of current through said tube and by pass, a motor for driving said generator.

3. A device of the character described ineluding a ventilating tube, a current generator associated therewith and adapted to create an air current therethrough, a turbine associated with the tube, a valve controlling the application of said current to the turbine, a by-pass carried by the tube around said turbine and valve, a fan operatively connected with and adapted to be driven by the turbine.

4. A device of the character described ineluding a ventilating tube, a current g enerator associated with the tube, a motor for driving said generator. to create a current through said tube, av turbine associated with said tube and adapted to be driven by said current, a fan operatively connected with and adapted to be driven by said turbine, and propellers operatively connected with and adapted to be driven by said motor.

5. A device of the character described ineluding a ventilating tube, a current generator associated with the tube, a motor for driving said generator, to create a current through said tube, a turbine associated with said tube and adapted to be driven by said current, a fan operatively connected with and adapted to be driven by said turbine, a propeller operatively connected with and adapted to be driven by said motor and means for reversing the direction of rotation of said propeller.

In testimony whereof I have signed my name to this specification.
